Definitions
- the present invention relates generally to a carrier for an IC package. More specifically, the invention disclosed herein describes a slide lock carrier device that utilizes slidable latches located at the corners of the device that secure an IC package within the device for testing and handling, and further offers reliability and space saving advantages compared to previous devices.
- Carriers for IC packages are generally well known in the art, although their modes of operation differ greatly.
- U.S. Pat. No. 5,249,972 discloses a pair of spring loaded pressure members that retain an IC package within the carrier, while the carrier in U.S. Pat. No. 5,290,193 utilizes a hinged cover that rotates over the IC package and secures it in place.
- Other prior art devices such as U.S. Pat. Nos. 3,963,315 or 4,222,090 employ separate sliding clips to clamp the IC package to the carrier body.
- the carrier disclosed in U.S. Pat. No. 5,292,266 secures the IC package with clips attached to torsion bars. Still other devices use a variety of sliding or hinged clamps.
- IC carriers should be both durable and easy to operate.
- problems with some of the prior art devices include clips that are subject to breakage after repeated use, or clips that are easily pulled off of the device during loading of the IC package.
- Many of the retaining methods are overly complicated, involving spring loaded hinged covers, while still others simply require too much space and are more difficult to manipulate when the IC package is being inserted into the carrier.
- the present invention functions without the drawbacks inherent in the prior art devices, and utilizes a plurality of linearly retracting sliding latches or clips to secure the IC within the carrier.
- the main body of the device defines a central recess for placement of the IC package, which is secured to the base by the retaining latches located at the corners of the main body.
- Each retaining latch has a finger that overlaps an adjacent corner of the IC package, with each latch being housed in a guide slot integrated into the main body of the carrier. The latches slide toward and away from the IC package in order to retain or release the IC package, respectively.
- FIG. 1 is a perspective view of a IC carrier device showing an IC package ready for insertion into the carrier device;
- FIG. 2 is a perspective view of the device shown in FIG. 1 showing the IC package disposed and secured within the device;
- FIG. 3 is a top plan view of the device as shown in FIG. 2;
- FIG. 4 is fragmentary sectional view taken along line 4--4 in FIG. 3;
- FIG. 5 is fragmentary sectional view like FIG. 4 but showing the latch of the device in its release position and the IC carrier being lifted from the device;
- FIG. 6 is fragmentary sectional view taken along line 6--6 in FIG. 5;
- FIG. 7 is a top plan view of the latch made according to the present invention.
- FIG. 8 is a side elevational view of the latch shown in FIG. 7.
- FIG. 9 is a front elevational view of the latch shown in FIGS. 7 and 8 seen along line 9--9 in FIG. 8.
- Base member 12 includes a central recess 16 located therein having multiple corners 18.
- Recess 16 is shown to be square and sized to receive an IC package 20 having complemental multiple corners 24.
- a plurality of slidable latches 22 are located at the corners of base member 12 and are each positioned to overlie an adjacent corner 24 of IC package 20 when the package is placed in recess 16 and supported upon shoulder 14 of the base.
- Each corner 24 has an open slot 26 serving as a guide passage for a latch 22, defined by guide flanges 44 and 46, end wall 62, and slotted floor 48, which is shown in FIG. 6 as a rib for ease of manufacture.
- bottom surface 54 of each guide flange 44, 46 contains an inward lock notch 56 and an outward release notch 58.
- Each latch 22 includes a finger portion 28 and a body portion 29.
- Each latch 22 further includes spaced feet 32, 34 and a cantilevered spring arm 38 at each side which extends from one foot 34 towards the other foot 32.
- a latch 22 is complementally disposed within each guide slot 26, with its spaced feet 32 and 34 interposed within between slotted floor 48 and bottom surface 54, and with its body portion 29 interposed between guide flanges 44 and 46 of base member 12.
- Body portion 29 of latch 22 abuts against outer wall 62 when latch 22 is in the release position.
- Top 60 of each cantilever arm 38 engages lock notch 56 or release notch 58 when the latch 22 is in the lock position or the release position, respectively.
- each latch 22 is pushed outward to its release position, thereby allowing IC package 20 to be inserted into recess 16 without interference from finger portion 28 of the latch, so that IC package 20 rests on shoulder 14 of base 12.
- the top 60 of cantilever arm 38 engages release notch 58, and body portion 29 is located next to outer wall 62 of guide slot 26, thereby preventing latch 22 from becoming disengaged from base member 12.
- each latch 22 is pushed inward towards a corner 24 of IC package 20 so that finger portion 28 of each latch 22 overlies the adjacent corner 24 of IC package 20 to secure the IC package to base member 12 of device 10.
- top 60 of cantilever arm 38 engages lock notch 56, thereby locking finger portion 28 of latch 22 in securing engagement with corner 24 of IC package 20.
